The invention relates to a BLDC remote control system of a wide bandgap semiconductor device based on mobile phone APP Bluetooth. The system comprises a mobile phone APP, a hardware controller, a motor body and an information real-time feedback module, wherein the mobile phone APP is in Bluetooth connection with the hardware controller and is used for issuing a control command to the BLDC motor body through the hardware controller and displaying various operation parameters of the BLDC motor body to a user according to the real-time operation condition of the BLDC motor body; the hardware controller is in Bluetooth connection with the mobile phone APP and is used as a controller to control the BLDC motor body to work; the BLDC motor body is connected with the hardware controller and is used as a driving control object; and the information real-time feedback module is used for detecting related operation parameter information of the BLDC motor body and feeding back the related operationparameter information to the mobile phone APP in real time. Compared with the prior art, the system has the advantages of meeting the requirement of the permanent magnet brushless direct current motor for high-speed control and the like.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to a BLDC remote control system of a wide bandgap semiconductor device based on mobile APP Bluetooth. Background technique [0002] With the advent of high-performance permanent magnet materials and the continuous improvement of power electronic control technology, permanent magnet motors have been widely used in various fields, and the representative permanent magnet brushless DC motor (BLDC) is one of them. BLDC overcomes the congenital defects of brushed DC motors and replaces traditional mechanical commutation with electronic commutation. It not only has the advantages of simple structure, reliable operation, and convenient maintenance of AC motors, but also has excellent speed regulation performance of DC motors. [0003] In recent years, remote monitoring technology has been widely used in all walks of life, and the power industry, as the foundation of the national economy, is ...
